Using the Overview Map
Overview
The Overview window displays a small map with a larger extent
than the current map. The current map's extent is shown
in this window with a red rectangle.
- Expand the Overview Map window by clicking on the
in the bottom left corner of the page.
- As you zoom the map in or out, the Overview map's extent may change so it shows an area somewhat larger than the
main map.
- The Overview map may look different from the main map.
Layers may be visible at different map scales (zoom levels).
Also, if the website uses multiple map services, only one will
display in the Overview map.
